Product details

The Stainless Bros 3D-printed 3-to-1 merge collector is precision-engineered from INC Alloy 625 using advanced metal additive manufacturing. Featuring a 17° merge angle, the internal geometry is optimized for efficient exhaust pulse convergence while maintaining high gas velocity in a compact, race-focused design.

This collector incorporates a butt weld and is welded to the tube directly.

If you’re searching for a billet merge collector or CNC billet collector, this advanced 3D-printed stainless steel merge collector represents the next evolution in collector design. While traditional billet collectors are limited by CNC machining and straight-line tool paths, additive manufacturing enables complex internal geometries that billet collectors simply cannot achieve. The result is smoother internal transitions, improved exhaust scavenging, reduced flow separation, and higher overall efficiency compared to conventional billet collectors.

*Designed to integrate seamlessly with Stainless Bros INC Alloy 625 elbows and tubing.

FOR THE SHOP. AND EVERYTHING AFTER.

FROM ONE BUILDER TO ANOTHER.

I started Keystone because I like making things. That’s still what drives it, and it’s who I have in mind when I add something to the shop.

MAKE IT PART OF YOUR EVERYDAY.

A tool you keep within reach. A shirt you grab on Saturday morning. Sometimes it’s the simple stuff that finds a permanent place in your routine.

THERE’S A PERSON BEHIND KEYSTONE.
